PIPE CUTTING AND THREADIN G TOOL.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed May 26, 1906. Serial No. 318,926.

To all whom it may concern:

Be it known that I, GEORGE W. NYE, a citizen'of the.

United States, residing at 731 Carmen avenue, in the city of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Pipe Cutting and Threading Tools, of which the following is a specification.

My invention relates to that class of tools operated by hand in cutting and threading pipe used in gas, water and steam fittings.

The object of my invention is to produce a simple, cheap and convenient pipe cutting and threading tool adjustable to the several sizes of pipe; and that can be instantly changed so as to be used for either cutting or threading purposes.

The manner in which I accomplish my object is described in the following specification and illustrated in the accompanying drawings in which:

Figure l is a face view showing the cutter lever closed. Fig. 2 is an end view showing the cutter lever open and closed the full lines illustrating the closed position as shown in Fig. l, and the dotted lines showing the open position of the same parts. Fig. 3 is an end view showing the threading die in position, and the cutter lever closed. Fig. 4 is a top View of the pipe cutter end, the cutter lever being closed. Fig. 5 is a central section on the line 5 5 Fig. 2. Fig. 6 is a cross sectional view on the line 6 6 Fig. 4. Fig. 7 is a perspective view of the pipe cutter end showing the bushing in position.

In the drawings A is the main body, this is preferably cylindrical in form, the ends Al being enlarged to afford the necessary thickness of metal. In the center of the length of the main body are two threaded holes A2 adapted to receive and hold handles A3. The interior of this body is cylindrical, the central part B being adapted to receive the largest size tube for which the tool is designed.

The end part B1 is enlarged and adapted to hold a removable bushing C. The other end B2 is also enlarged and adapted to hold a removable threading die D. As many bushings and dies are used as there are differences of size in the pipes designed to be cut and threaded. In the side of each bushing is a channel C1 adapted to correspond with a like channel AM1 in the main body. In the periphery C2 of the bushing are recesses C3. Set screws A5 in the main body engage the bushing in these recesses and hold it in position therein. There are similar recesses D1 in the die, and set screws A5 in the main body adapted to engage the die in these recesses and hold it in position. The dowel pins D2 prevent the die from turning in its position. The interior of the main body at B3 is larger than the central part B and is adapted thereby to allow space for the material cut from the largest size pipe to move in advance of the face of the die when the pipe is being threaded.

Forming part of the body A are projections Al and A7. Pivotally attached to the projection A is a lever E, constructed of two parallel bars El. Supported between these bars on a transverse shaft E2 afiiXed in said bars is a circular pipe cutter E3. The lever E pivoting on the pin E4c is adapted to be moved into and out of the channel AL in the main body and channel C1 in the bushing C. Pivotally supported on the projection A7 is a threaded bolt F and thumb nut F1. This bolt and nut is pivoted on the pivot pin F2 and is adapted to be moved into and out of engagement with the open free end E5 of the lever E when it is in the channel A4, and to be used for the purpose of applying pressure to said lever and thereby forcing the cutter E3 into the pipe in the operation of cutting a pipe.

When the tool is constructed as described and the several parts are in the closed position as shown in the several figures it is used as follows: The thumb nut F1 on the bolt F is reversed and both are moved out of engagement with the open end E5 of the lever E as shown by the dotted lines in Fig. 2. The lever E is then lifted out of the channel in the bushing and main body, and moved back into the position as shown by the dotted lines in Fig. 2 and full lines in Fig. 5. If a pipe is to be cut and its length requires the die D is 'removed to let the pipe pass through. The handles being adjusted, the tool is then slipped over the pipe G which is held in a pipe vise or by oth er means. The lever E is then moved into the closed position the cutter E3 resting on the pipe. The bolt F and thumb nut is then moved into engagement with the open end of the lever E and the nut is screwed down, and the cutter is thereby forced into the pipe. The pressure applied by the nut is maintained on the lever as the body A is rotated about the pipe, by the turning of the thumb nut till the cutter is forced through the pipe. A reversal of the movement of the thumb .nut releases the lever, which is then raised out of the channel in the main body and bushing.

For threading pipe, the bushing and die adapted in size to the pipe to be threaded are inserted in the body A, and the bushing end slipped over the pipe first, the die is adjusted on the end of the pipe and rotated by one or more handles secured in the main body. For

convenience in carriage, the handles are removed from the main body.

What I claim and desire to secure by Letters Patent is:

"1. A device of the kind described, consisting of a main hollow cylindrical body adapted internally to hold a busl1- ing'y said body having radial apertures for the insertion of handles, and an external transversechannel to admit a cutter lever intermediate of one end of said body and the radial apertures therein, transverse projections on opposite sides of said body in line with the central length of said channel, an open ended cutter lever and circular disk cutter centrally supported in said level', said lever being pivotally secured to one of said projections and adapted to be moved vertically in said channel, a threaded bolt piv otally secured to the other projection, a thumb nut on said bolt, said bolt and nut being adapted to engage the open end of said lever and toA press saidlever down into said channel, a cylindrical bushing having an external transverse channel adapted to correspond with the channel in the main body, said bushing being; insertible in said main body, and a pair of handles insertible in the radial apertures in said main body as described,

2. ln adevice of the kind described, the combination with a main body adapted internally to support a bushing, and having, an external transverse channel, and radial apertures adapted i'or the insertion ot operating handles; of a bushinginsertible in said body, said bushing having au external transverse channel adapted to register with said channel in said body, means for securingl said bushingY in position in said body a lever secured at one end to said body, adapted to [it said transverse channel in said body and bushing and to support a circular cutter; a circular cutter rotatably supported in said lever; and means for moving said lever and cutter vertically in said channels, as described.
